whyin FullMesh topology if one device fails data traveling along network can be routed through another device?

Question

can any one give me full answer plz

Answer 1

Full mesh topology occurs when every node has a circuit connecting it to every other node in a network. Full mesh is very expensive to implement but yields the greatest amount of redundancy, so in the event that one of those nodes fails, network traffic can be directed to any of the other nodes. Full mesh is usually reserved for backbone networks.
